Section 1 Burner Orifice Plate Replacement (all models).
Step 1: Remove the four retaining screws securing the burner casting using a no. 2 crosshead screwdriver.
Step 3: The burner head assembly can now be disconnected by separating the connectors of the ignition and flame probe lead assemblies and removing the ground lead and pressure switch silicon tube.
Step 2: Remove the supporting casting and gasket.
Step 4: The burner orifice plate can then be released by removing the 3 fixing screws from the burner tube using a No.2 crosshead screwdriver.
Step 5: Using a flathead screwdriver remove the retaining washer securing the impulse stud (arrowed). Remove the stud. Remove the cable grommet from the old orifice plate and attach to the replacement plate.
Step 6: Fit new propane burner orifice plate to burner tube ensuring the impulse stud is facing the correct direction. The cable grommet is fitted to the lower of the 3 holes at the bottom of the plate (arrowed). Two new gaskets are provided and should be used when reconnecting to the burner housing. Dispose of the old gaskets.
See Section 13 for correct burner orifice plate identification.
Section 2 Turbulator Information.
These heaters have a different arrangement of turbulators and tube inserts when operating on LPG. This section will guide you through the process of changing these components where necessary.

Figure 2: Turbulator Length 4 3" (1277mm) Part No. 270495 (202422)
Step 1: Prior to conversion a number of the natural gas heaters use a tube insert Part No. 270489 (201688) See Figure 1. This is not required when operating on LPG, please check inside the firing leg. If fitted, remove and discard.
Step 2: If your heater is a 20’ long model, fit the turbulator Part No. 270495 (202422). See Figure 2. (Note: This turbulator is already fitted to the 20’ VPT/VCT heaters)
Section 3 Flame Plate Attachment (all models).
Step 1: Remove the 3 screws holding the burner head in place with a no. 2 crosshead screwdriver. Step 2: Discard the spacer bracket arrowed below.
Step 4: Attach flame plate to the burner tube using the 3 screws removed in step 1. Ensure the flame plate is mounted ON TOP of the original burner head.
Step 3: Align the 5 holes in the flame plate (arrowed) with the 5 holes on the outer edge of the burner head as shown.
